Page 18 - Joyce - Jacks, actuators and systems

Versatile Joyce machine screw jacks lift and precisely position
all kinds of loads from 250 pounds to 250 tons.
Upright or inverted, these precision jacks operate at full
capacity whether the load is in tension or compression.
WJ and RWJ series single lead jacks are self-locking under
full lifting capacity. DWJ and DRWJ double lead series jacks
offer increased travel speed.
Alloy steel input shafts, aluminum bronze wormgears and
tapered roller or ball thrust bearings provide rugged reliability.
Double input shafts are standard. Single input shafts are
available with right or left hand extension or additional length.
Jacks are available with one of four standard end conditions
or special ends to meet your requirements. All jack designs
can be fitted with protective boots.
An optional anti-backlash feature (pages 180 and 181)
compensates for thread wear, assuring minimum play between
lifting screw and wormgear for smooth, precise operation. Jacks
equipped with the anti-backlash feature are rated at full capacity
under static conditions. For anti-backlash jack capacity under
dynamic conditions, please contact Joyce/Dayton.

Joyce/Dayton can customize machine screw jacks to meet
your specifications.
